Relative Tolerance of legumes AND OTHER CROPS TO SOIL ACIDITY

May 1941
Rep. May 1952 (5C)
No exact pH can be given for any crop. Some crops will grow on acid soils and yet respond to lime. Acid tolerant crops like lespedeza will do better on limed land, but may not compete with rank-growing, lime-loving crops on sweet soil. The supply of plant food and organic matter in the soil have a marked influence on the need for lime.
